A kind of production process of turning needle

Abstract

The invention discloses a stitch transfer piece production process, and belongs to the technical field of machining of computerized flat knitting machine parts. A traditional stitch transfer piece production process has the problems of low wear resistance, poor toughness and the like, and shortens the service lives of knitting needles and the stability of equipment. The machining process of the invention re-optimizes the material of a stitch transfer piece, and selects T10 alloy steel with better performances. In addition, repeated heat treatments are performed on loom-state fabrics to reducethe deformation of the loom-state fabrics and refine the metal interior metallographic structure so as to further eliminate internal stress. Finally, the accuracy, toughness and appearance quality ofthe stitch transfer piece are greatly improved through the correction treatment and coating treatment of a working part so as to prolong the service life of the stitch transfer piece, improve the economic value of products, and provide a foundation for quality improvement of subsequent knitting products to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of processing parts of a computerized flat knitting machine, and in particular relates to a production process of a transfer piece on a knitting needle. Background technique [0002] The knitting needle is one of the important parts of the knitting mechanism on the computerized flat knitting machine. It is mainly used to complete related actions such as loop knitting, tuck knitting, transfer and non-knitting. The knitting needle is mainly composed of a needle body and a transfer piece. During work, the coil goes out from the knitting needle in one direction to the transfer height, and the coil falls to the transfer piece in the knitting needle. At the same time, the knitting needles at the corresponding position on the other needle bed are ejected to the height of the needle connection. The needle hook of the receiving needle is inserted into the transfer piece of the transfer needle, and after the needle i...

AI Technical Summary

Problems solved by technology

[0003] At present, the production process of the transfer piece on the market is basically stamped by T8 alloy steel strip, and then the finished product is formed after a heat treatment and shape grinding and polishing. However, the transfer piece produced by this process has insufficient wear resistance and poor toughness. problem, which shortens the service life of knitting needles and the stability of the equipment; secondly, in the production process of the transfer piece, because the transfer piece is relatively small and thin, it deforms greatly during the heat treatment process, and once deformed, it cannot be repaired, reducing the Improve the pass rate of the product and increase the production cost of the enterprise
